Detuned Harmonic Filter: Detuned filter are used, in supply networks having a high level of harmonic distortion, when the final objective is reactive power compensation at the fundamental frequency. Their purpose is to avoid the harmonic currents overload to the capacitors by diverting them to the mains. Protection filters are made by connecting reactors in series with capacitors, in such a way that the tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonics, which is usually the 5th order harmonic. In this the filter has a high inductive impedance for all the harmonic frequencies.

INA/INR reactors are designed to work in supply systems with a high level of harmonic distortion in such a way that they allow a safe and reliable service of the power factor detuned, so that, the whole unit has an inductive are specially designed to work in series with FMF capacitors correction equipments. Reactors are connected in series with power capacitors, forming a resonant circuit conveniently.Connection of a reactor in series with a power capacitor, makes the capacitor to work at a voltage higher than the supply voltage. Because of this, capacitors need to be connected to protection reactors and need to be designed to work at higher voltages than standard capacitors. The choice of the tuning point of the filters is to balance between the quantity of harmonics rejected by the filter and the voltage increase produced in the capacitor at the fundamental frequency.It is to be also kept in mind that reactive power supplied by the filter at rated frequency (50 or 60 Hz), is different to the one that the capacitor would supply without the reactor. Taking all the above into account, the reactor is normally chosen in such a way that its impedance is about 7% of the impedance of the capacitor that protects. This will give a tuning frequency, for example at 50 Hz, of 189 Hz. Other tuning frequencies are also available.

Third Harmonic Filter

Approx Price: Rs 300 / Piece 
Product Details:
  • Size: as per customer requirements

Third Harmonic Filter is basically passive filters with a parallel combination of inductance and condenser. The advantages of third harmonic filter are:

  • Reduction of the third overtone until a 90%.
  • Significant Reduction of other overtones.
  • Reduction current of neutral absorbed.
  • Reduction of losses in the installation.
  • Reduction of the interferences.
  • Improvement of the power factor.


    Filter HBF-T has to be selected in agreement with the current of the breaker that protects the circuit. They are connected in the neutral conductor of the three-phase installation, and it is possible to be seen in scheme 1.

    Product Details:
    • Material: As per customer required
    • Size: as per customer requrement

    Passive Harmonic Filter are used on distribution networks which have a high THD (Total harmonic distortion), when the final target is to compensate the power factor at the fundamental frequency.Its purpose is to avoid overloads due to harmonic currents in the capacitor, deflecting them to the network.Protection filters are made with serial reactors and capacitors. The tuned frequency of each unit is adjusted between the fundamental and the lower harmonic present in the net, which usually is the 5 th order.In this way, the filters present high inductive impedance for all the harmonic frequencies.
